upcp, the cPanel update script, has a flag, "--force." What does it do? When should I use it?
upcp --force tells the update script to update no matter what, even if updates are set to Disabled, or if your server is still set to wait during a staged rollout.
Be warned, this flag will update to the latest version available in your current tier. You can view your current tier in the WHM interface > Update Preferences, or via the command line:
# cat /etc/cpupdate.conf
